|---|---|---|---|
| 설명 | 인간이나 동식물의 건강-생활에 피해를 주는 인위적 발생원으로 인해 대기가 오염된 상태. 인간사회의 생산-유통-소비의 각 과정에서 배출되는 대기오염물질에 의해 사람의 건강은 물론 동식물-토양-지형-기후-수리 등으로 얽힌 생태계의 안정성이 방해될 때를 대기가 오염되었다고 한다. 여기에서 대기오염물질이란 대기의 조성을 변화시켜 인간사회나 생태계에 영향을 미칠 정도로 존재하는 천연 또는 인공물질을 말하며, 고체-액체-기체 또는 이들의 혼합물이 포함된다. 단일한 물질만으로 된 대기 오염물질은 드물며, 일반적으로는 많은 종류와 크기로 된 복합물질이다. 크게 나누면, 특정한 발생원에서 직접 방출되는 일차 오염물질과, 두 종류 이상의 일차 오염물질에 의한 상호작용이나 광화학반응 등에 의해 생긴 이차 오염물질이다. 매연, 먼지, 일산화탄소 따위와 같은 물질이 공기와 섞이는 일이 대기오염의 예이며, 그뿐 아니라 이산화탄소의 증가로 인하여 지구의 온난화, 그리고 프레온 가스로 인한 오존층의 파괴 따위가 문제시되고 있다. |

| barrel of oil equivalent | A unit of energy equal to the amount of energy contained in a barrel of crude oil. Approximately 5.78 million Btu or 1,700 kWh. A barrel is a liquid measure equal to 42 gallons. (05 Dec 1998) |
| gold equivalent | A unit of power of the protective colloids; the number of milligrams of protective colloid just sufficient to prevent the precipitation of 10 ml of a 0.0053 to 0.0058% gold solution by the action of 1 ml of a 10% sodium chloride solution. Synonym: gold number. (05 Mar 2000) |
| gram equivalent | The weight in grams of an element that combines with or replaces 1 gram of hydrogen, the atomic or molecular weight in grams of an atom or group of atoms involved in a chemical reaction divided by the number of electrons donated, taken up, or shared by the atom or group of atoms in the course of that reaction, the weight of a substance contained in 1 liter of 1 normal solution; a variant of. Synonym: combining weight, equivalent weight. (05 Mar 2000) |
| metabolic equivalent | The oxygen cost of energy expenditure measured at supine rest (1 MET = 3.5 ml O2 per kg of body weight per minute); multiples of MET are used to estimate the oxygen cost of activity, e.g., 3 to 5 METs for light work; more than 9 METs for heavy work. (05 Mar 2000) |
| roentgen-equivalent | <radiobiology> A unit of dose equivalent to that quantity of ionizing radiation of any type that produces in man the same biologic effect as one rad of X-rays or gamma rays; the number of rems is equal to the absorbed dose, measured in rads, multiplied by the quality factor of the radiation in question.100 rem = 1 Sv. (05 Mar 2000) |
| roentgen-equivalent physical | <radiobiology, unit> A roentgen equivalent physical is a unit of absorbed radiation approximately equivalent to a roentgen, an international unit of x- or gamma-radiation. An obsolete unit of measurement; that quantity of ionizing radiation of any kind which, upon absorption by living tissue, produces an energy gain per gram of tissue equivalent to that produced by 1 roentgen of X-rays or gamma-rays. Acronym: rep See: rad. (05 Mar 2000) |
| combustion equivalent | The heat value of a gram of carbohydrate or fat oxidised outside the body. (05 Mar 2000) |
| starch equivalent | The amount of oxygen consumed in the combustion of a given weight of fat as compared with that consumed in the combustion of an equal weight of starch; the figure is about 2.38, that for starch being taken as 1. (05 Mar 2000) |
| nitrogen equivalent | The nitrogen content of protein; used in calculating the protein breakdown in the body from the nitrogen excreted in the urine, 1 g of nitrogen considered as having originated in 6.25 g of protein catabolised. (05 Mar 2000) |
| toxic equivalent | The amount of toxin or other poison per kilogram of body weight necessary to kill an animal. (05 Mar 2000) |
| equivalent | Having the same value, neutralising or counterbalancing. Origin: L. Aequivalens, from aequus = equal, valere = to be worth (11 Nov 1997) |
| equivalent dose | In radiation protection, the absorbed dose averaged over a tissue or organ and weighted for the quality of the radiation of interest. The unit of equivalent dose is the sievert. (05 Mar 2000) |
| equivalent extract | A fluidextract of the same strength, weight for weight, as the original drug. Synonym: valoid. (05 Mar 2000) |
| equivalent focal length | <microscopy> The focal length of the simple lens that has the same power as the compound lens. The stated focal lengths of microscope objectives are the equivalent focal length since their front and back focal lengths are very different. (05 Aug 1998) |
